Nvidia (NVDA) RTX Spark CPU Performance Trails Apple's M3 by Two Years

Nvidia (NVDA) unveiled its RTX Spark Superchip on June 6, 2026, but leaked benchmarks indicate its N1X CPU's performance matches Apple's 2023 M3, about two years behind the M5. The 20-core N1X engineering sample scored 3,096 single-core and 18,837 multi-core in Geekbench tests, versus Apple's M3 Max at 3,128 and 20,969. M5 reaches 4,224 single-core and M5 Max nearly 30,000 multi-core. The RTX Spark integrates CPU, GPU, AI accelerators and up to 128GB of unified memory, mirroring Apple's architecture. Nvidia says it can run 120-billion-parameter large language models locally. While CUDA and Blackwell GPU may offer AI advantages, CPU performance trails, pending final product improvements.
